Principles of Plasma Diagnostics by Ian Hutchinson was first published in 1987 and the second edition was published in 2003.

The first chapter is an introduction to particle distribution functions. An important concept in plasma diagnostics. Chapter two focuses on magnetic probes and issues around flux measurements in magnetically confined plasma.

Chapter three is a comprehensive discussion on electrical probes. While the work is a little dated this is a solid chapter and one of my favorites books on probe diagnostics. It is good for someone starting out in plasma diagnostics. I would think that it stops short of a complete discussion on the latest techniques.

Chapter 4 discusses optical diagnostics. This is a very comprehensive discussion of the more basic techniques and represents a good introduction to the new student of plasma diagnostics. The next two chapters focus on emissions from free and bound electrons. The final two chapters complete the optical diagnostics and a very comprehensive chapter on neutral particle measurements and fast ions.

The second half of the book is more suitable to Fusion type studies than the industrial type non-equilibrium plasma but overall this is one of the best books available on plasma diagnostics.
